In regard of accessibility this is indeed critical: Bold i is difficult to distinguish from l. This can be clearly seen when bold i is compared to normal i and e.g. i in HTML anchors (see menu). The latter are easy to read compared to bold i in the text.

Checked with Firefox 49.2 on a 1400×1050 TFT monitor. Font according to FF is LibreFranklin-ExtraBold.

Sorry, but why is this issue “resolved”? The “l” instead of “i” is still there. Checked on several operating systems, screens and browsers in default zoom status.
Curious: in FF with “Strg +” / one step bigger it becomes a correct and readable “i” AND with “Strg -” / one step smaller as well.
